Have same problem with my Citiz

SOURCE: the milk doesnt heat up

We had the same problem with burn marks on the bottom and flashing red light etc. Now we just rinse the container out with cold water each time we use it - do not dry, just leave it wet and then add your milk. Heats up perfectly each time. The water lubricates the base of the container, preventing burning. Nice hot coffee every time now. Hope this works for you too!
